@zadjii-msft commented on GitHub (Nov 13, 2023):

based on the linked thread, I'm gonna say this is /dup #16051

There was a bug in Terminal's env var generation, which only manifests when there's a embedded NUL in one of the env vars: https://github.com/microsoft/terminal/issues/16051#issuecomment-1764546234

We should be hotfixing that sometime this week

I have started receiving this error today after updating windows Terminal to 1.19.10292.0.

I'm executing the following command via an Elgato Stream Deck

wt pwsh -ExecutionPolicy bypass -WindowStyle normal -file "C:\repos\ff-screenshot\screenshot.ps1" -outputDirectory "\\192.168.2.5\a-sexy-renderer\drive\My files\pictures\ff-screenshot" -saveToDirectory y -copyToClipboard y -captureDevice "Video (00-1 Pro Capture Dual HDMI 4K+)" -bypassQuit y

The Get-EnvsWithEmbeddedNull.ps1 PowerShell script linked in https://github.com/microsoft/terminal/issues/16051 prints nothing for me. Uninstalling and re-installing Windows Terminal via Winget in PowerShell ISE did not fix the issue.

This script/command has never given me issues until now... I'm completely lost, with seemingly no method of fixing this issue.

Good to hear there's a fix, unfortunately I am unable to pull said update via winget or Microsoft Store even now.

I may just have to pull the zip from the repo and use PowerShell to move the files to WindowsApps.

Edit - jk there's a msixbundle option on the repo.
